To all 'zc/'wm it may concern;

Be it irnown that we, DA-VlsW. ENTRIKIN and Levis H. nAvis, or West Chester, in .the

4 tion of the constructipn and operation of' the saine, reference beingghad--to the annexed drawings, forming part of this specification,

' 2 is a side elevation of the same.' [Fig 3 is a view showing elevating-lever andparts connected therewith. Fig. 4 is arear view of frame.

Fig. is a sectional view, showing construction of reel. Fig. G is a cross-section of internal gear-wheel and pinion driving cutting apparatus. Fig,7isacross-sectionof t ongue,. show` ing,` rollers above and below.. l Similar characters of reference denote the Our improv-ement has reference lto the manner of .elevating and lowering the cutter-bar,

and to the lmanner of throwing the cutting ap- "=pa1at us into and out of gear, the 'details ot' con# struction and operation being as hereinafter Iset forth.

lnlthe drawings, F is the main frame, P f ythe platform, and B the linger-bar. Theshaft ofthe main driving-wheel Wrests-.in bearings 'f` a a onv the gear-frame F', and iscapable of a i longitudinal motion in said bearings to regulate the meshing .of teethc' and pinion b on 'shaft c. l rlhis movement of the shaft A and main driving-wheel W i's produced -by the action of a crank, d, in a slot,e, ot' aflange,f, on a slide-piece, g. This piece rests against a shoulder, b, of the shaft and a pin', 0'-, so as to 'j' move the shaft and wheel by power applied to -lever d at the head ofthe aforesaid crankshaft.

lA rapid recipepcatiou `is given to the cutter fijnbar by iueans'offthe internal gear on shaft c, with which thefpinion e' on the head of shaft meshes. At the opposite extremiyof shaft is'the wheel gf, with which the outter-baris ccentrcally connected by rod kl. Hooks h on tandards h" serve to' hold lever d in position.

fhe draft-tongue C is attached to the frame .F by a bolt passing through lugsr'h i and runs iorward between two upright plates, .7i The.

v(tongue, a lever,.l', being secured to the shaft Zt on the opposite side ofthe said tongue. Te the rear extremity of the curved piece l) is se cured a chain., E, passing over a pulley, G, on the side'of the tongue and secured to the front of the frame F', so that by the .movement vof Upon the tongueis a curved ratchet, H,1by which the pawl m on thelcver l holds the tin- 'as a rod, ,inpassing through an eye, 0'hy which itis lifted from the ratchet.

isgiven to side pressure, and

prevent friction in the vertical movement of the front portion of the machine. -Th e' front of the tongue is supported by a easter-wheel, WV'.

The pole B.l is attached to' the tongue bya bolt, t", passing through two sets otf lugs, j

and the otheron the pole. Thereis a projecto be' so attached that the outside of lug 'k' npof lugj on that side, thereby movingthepole changeis advantageous when converting the machinefipni a mower to a reaper.

will enable 'it to resist the pressure against the cutting apparatus.

the shaft and pulley q on the driving-wheel.

The reel-head is constructed in the following manner: The shaft passes entirely through the head and has a screw-thread cuton its exaxis o't` the bolt by which the tongue is attached 'to the lugs is above the axis ot' the axle A of` theni'ain wheel W, so that in 'backing the machine there will he a'constant tendency to lift the cutter-bar over obstructions'. it also draws D, secured to a shaft,-k, passing throughjtheV lever l the linger-barB will be inoved vertically; gerbar 'atany desired elevation. This pawl.'

f Above and below the tongue are wheels jo 19. slightly smallerthan the space-between the plates jj. By these wheels a broad bearing v e tongue prevented from twisting; and these wheels act to and k', the one on the extremity ofthe tongue v tion, o', on the in ner side of the pole to give vthe space between lugs k' the samexas the distance between lugsj., --This permits the pole .l

tremity. Secured to the shalt is the plate cut out to receive the arms u. A collar, V, is then slipped upon the shaft, cut out on one side to hold arms u, and on the other side formed with a concavity to receive the oblique arms u', upon which the conical cap' X is forced by nut q. This cap, being forced to a firm bearing, e'ectually clamps the arms u u to the head of the reel, thus rendering the reel capable of being taken apart for purposes of transportation.

The cross-piece M, which -forms the rear of .the main frame, and which supports the rear ofthe platform when the machine is designed as a reaper, is bolted under the side pieces of the frame. VVihen the platform is removed ,this piece is to be bolted upon the aforesaid side pieces sofas to give additional space be.-

twjeen its under surface an'd the ground. vIt isl necessary that this piece have the low position when supporting the platform, in order that thevplatform may be level; but when lthe platform is removed the bar:l is then too low for mowing purposes. V' Jhe machine'is therefore constructed withthe side pieces ot' the'frarn'e extending rearward and permitting thel bolting of piece M either upon their upper or lower faces, thesame vboltholes serving for both s.; 'were 2.' The combination ofthe slotted slide-piece upon the main axle with the crank workingin said slot, substantially as and for the purpose set forth. p
